Description

Technical Field

[0001] This utility model relates to the field of packaging film technology, specifically to an anti-slip roll packaging film. Background Technology

[0002] Packaging film refers to thin films used for packaging goods. These films are mainly used for packaging food, pharmaceuticals, and textiles. They possess puncture resistance and high strength, and are non-toxic. Packaging film is widely used for the external packaging of products in industries such as foreign trade export, papermaking, hardware, plastics and chemicals, building materials, food, and pharmaceuticals. Its non-toxic, transparent, and flexible properties make it an ideal material for food, daily necessities, and small-packaged goods in supermarkets. Packaging film is a chemical product used for packaging filling, providing pressure resistance, moisture protection, and shock absorption. It has advantages such as good shock absorption, impact resistance, heat sealing, non-toxicity, odorlessness, moisture resistance, corrosion resistance, and good transparency. To improve the efficiency of goods packaging, a roll packaging film is needed. However, existing roll packaging films still have the following shortcomings:

[0003] When using existing roll packaging films, the relatively smooth surface of most roll packaging films and the relatively smooth surface of the goods result in relatively low friction between the roll packaging film and the goods during use. This makes the goods easy to slide during the packaging process, which affects the packaging progress and process, leading to a decrease in the practicality and efficiency of the roll packaging film.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a non-slip roll packaging film. Utility Model Content

[0005] The purpose of this invention is to provide an anti-slip roll packaging film to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip roll packaging film, comprising a main film body, an inner composite anti-slip agent layer, and an outer composite anti-slip agent layer. The main film body contains a substrate layer, with an inner composite anti-slip agent layer at its lower end and a polyurethane waterproof layer at its upper end. A polyethylene oil-blocking layer is connected to the upper end of the polyurethane waterproof layer. A polyvinyl acetate layer is provided above the polyethylene oil-blocking layer, and a polyvinyl alcohol layer is provided above the polyvinyl acetate layer. An outer composite anti-slip agent layer is connected to the upper end of the polyvinyl alcohol layer. An adhesive strip is added to the left side of the main film body, and release paper is added outside the adhesive strip.

[0007] Furthermore, the outer side of the substrate layer and the outer side of the inner composite anti-slip agent layer are horizontally distributed, and the outer side of the substrate layer and the outer side of the inner composite anti-slip agent layer are closely attached.

[0008] Furthermore, a polyvinyl acetate layer and a polyurethane waterproof layer are respectively provided on the upper and lower sides of the polyethylene oil-blocking layer, and the polyethylene oil-blocking layer is disposed and confined between the polyvinyl acetate layer and the polyurethane waterproof layer.

[0009] Furthermore, the outer side of the polyurethane waterproof layer and the outer side of the polyethylene oil-blocking layer are horizontally distributed, and the outer side of the polyurethane waterproof layer and the polyethylene oil-blocking layer are closely bonded together.

[0010] Furthermore, an outer composite antislip agent layer and a polyvinyl acetate layer are respectively provided on the upper and lower sides of the polyvinyl alcohol layer, and the polyvinyl alcohol layer is disposed and confined between the outer composite antislip agent layer and the polyvinyl acetate layer.

[0011] Furthermore, the outer side of the polyvinyl alcohol layer is horizontally distributed with the outer side of the main film body, and the polyvinyl alcohol layer is fixedly connected to the main film body by an adhesive.

[0012] Furthermore, the outer side of the adhesive strip is horizontally distributed with the outer side of the release paper, and the outer side of the release paper is closely attached to the outer side of the adhesive strip.

[0013] This utility model provides an anti-slip roll packaging film, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of an external composite anti-slip agent, enables the inner side of the main film to have good adhesion when the anti-slip roll packaging film is used, through the inner composite anti-slip agent layer. The polyurethane waterproof layer is fixedly set on the upper part of the outer side of the substrate layer, using the polyurethane waterproof layer to improve the waterproofness of the main film. At the same time, the polyethylene oil-blocking layer improves the oil-blocking property of the main film, preventing oil while maintaining the breathability of the main film. The polyvinyl acetate layer is set on the outside of the polyethylene oil-blocking layer, through which the polyvinyl acetate layer gives the main film flame-retardant properties, and the high barrier properties of the polyvinyl alcohol layer improve the heat insulation of the main film. The addition of an external composite anti-slip agent layer on the upper part of the main film makes the outer side of the packaging film also have anti-slip properties, preventing the goods from sliding during the use of the packaging film, and improving the overall practicality and efficiency of the packaging film.

[0015] 2. This utility model, through the setting of the adhesive strip, enables the adhesive strip to be fixedly installed on the outer left side of the main film body when using the anti-slip roll packaging film. With the help of release paper, the adhesive strip is blocked. After the packaging film is rolled up to package the goods, the release paper is peeled off and the main film body is fixed by the adhesive strip, which avoids the situation where the goods fall off the packaging film due to mismatch between the packaging box and the goods, and improves the dynamism and efficiency of the roll packaging film during use.

[0021] like Figures 1 to 3As shown, an anti-slip roll packaging film includes a main film body 1, an inner composite anti-slip agent layer 3, and an outer composite anti-slip agent layer 8. A substrate layer 2 is disposed inside the main film body 1, with the inner composite anti-slip agent layer 3 disposed at the lower end of the substrate layer 2. A polyurethane waterproof layer 4 is disposed at the upper end of the substrate layer 2, and a polyethylene oil-blocking layer 5 is connected to the upper end of the polyurethane waterproof layer 4. A polyvinyl acetate layer 6 is disposed at the upper end of the polyethylene oil-blocking layer 5, and a polyvinyl alcohol layer 7 is disposed at the upper end of the polyvinyl acetate layer 6.

The outer side of the inner composite anti-slip agent layer 3 is horizontally distributed, and the outer side of the substrate layer 2 is tightly bonded to the outer side of the inner composite anti-slip agent layer 3. Polyvinyl acetate layer 6 and polyurethane waterproof layer 4 are respectively provided on the upper and lower sides of the polyethylene oil-blocking layer 5, and the polyethylene oil-blocking layer 5 is positioned and confined between the polyvinyl acetate layer 6 and the polyurethane waterproof layer 4. The outer side of the polyurethane waterproof layer 4 is horizontally distributed to the outer side of the polyethylene oil-blocking layer 5, and the outer side of the polyurethane waterproof layer 4 is tightly bonded to the polyethylene oil-blocking layer 5. The upper and lower sides of the polyvinyl alcohol layer 7 are respectively provided with outer composite anti-slip agent layer 8 and... A polyvinyl acetate layer 6 and a polyvinyl alcohol layer 7 are disposed and confined between the outer composite anti-slip agent layer 8 and the polyvinyl acetate layer 6. The outer side of the polyvinyl alcohol layer 7 is horizontally distributed with respect to the outer side of the main membrane 1, and the polyvinyl alcohol layer 7 is fixedly connected to the main membrane 1 by an adhesive. The inner composite anti-slip agent layer 3 is fixedly installed on the lower outer side of the substrate layer 2 by the adhesive. The inner composite anti-slip agent layer 3 provides good adhesion to the inner side of the main membrane 1. The polyurethane waterproof layer 4 is fixedly disposed on the upper outer side of the substrate layer 2, and the polyurethane waterproof layer 4 enhances the waterproofness of the main membrane 1. The packaging film is designed to be breathable while maintaining its oil-resistant properties. A polyvinyl acetate layer 6 is placed outside the polyethylene oil-resistant layer 5, giving the main film 1 flame-retardant properties. Combined with the high barrier properties of the polyvinyl alcohol layer 7, the heat insulation of the main film 1 is improved. An external composite anti-slip agent layer 8 is added to the upper part of the main film 1, giving the outer surface of the packaging film anti-slip properties, preventing the goods from sliding during use, and improving the overall practicality and efficiency of the packaging film.

[0022] like Figure 1 and Figure 3 As shown, an adhesive strip 9 is added to the outer left side of the main film body 1, and a release paper 10 is added to the outside of the adhesive strip 9. The outer sides of the adhesive strip 9 and the release paper 10 are horizontally distributed, and the outer sides of the release paper 10 and the outer sides of the adhesive strip 9 are tightly attached. The adhesive strip 9 is fixedly installed on the outer left side of the main film body 1 by adhesive, and the release paper 10 is used to block the adhesive strip 9. After the packaging film is rolled to package the goods, the release paper 10 is torn off and the main film body 1 is fixed by the adhesive strip 9, so as to avoid the situation where the goods fall off the packaging film after the packaging box and the goods do not match, thus improving the initiative and efficiency of the roll packaging film in the process of use.

[0023] In summary, when using this anti-slip roll packaging film, the inner composite anti-slip agent layer 3 is first fixed to the lower outer side of the substrate layer 2 using an adhesive.

Then, the adhesive strip 9 is fixedly installed on the left side of the outer surface of the main film body 1 with adhesive, and the release paper 10 is used to block the adhesive strip 9. After the packaging film is rolled up to package the product, the release paper 10 is peeled off and the main film body 1 is fixed by the adhesive strip 9, which prevents the product from falling off the packaging film after the packaging box and the product do not match, and improves the dynamism and efficiency of the roll packaging film during use.
